FIELD: communication.
SUBSTANCE: invention relates to telecommunication, in particular to devices for evaluation of data communication in communication systems. Apparatus for evaluating efficiency of data communication of communication system comprises a unit of meter-computer of information transmission efficiency of a communication system, first and second counters, divider, comparator circuit, logarithm computer and a multiplier, as well as required connections between them.
EFFECT: technical result of disclosed device is high accuracy of estimating efficiency of transmitting information by taking into account when determining effect on communication system of interference by additional estimation of noise immunity and specification thereof by estimating efficiency of transmitting information.
